Extraction of protein from skim natural rubber latex using PEG as a surfactant via low speed centrifugation and continuous flow

13-09-2013 | Duangkamol Danwanichakul, Ornthana Rattanaphan, Jirarat Srisatjang, Panu Danwanichakul, Journal of Applied Polymer Science, 2013

ABSTRACT Protein extractions from skim natural rubber latex using 3 %w/v polyethylene glycol (PEG6000) via both low speed centrifugation and continuous flow were investigated. In centrifugal extraction, when the speed was 1000 rpm, the extractable protein (EP) content in serum increased with ...


Fibrinogen Monolayer Characterization by Colloid Deposition

10-09-2013 | Małgorzata Nattich-Rak; Zbigniew Adamczyk; Monika Wasilewska; Marta Sadowska, Langmuir, 2013

Colloid particle deposition was applied to characterize bovine and human fibrinogen (Fb) monolayers on mica produced by controlled adsorption under diffusion transport at pH 3.5. The surface concentration of Fb was determined by AFM enumeration of single molecules adsorbed over the substrate ...


Lectin-dependent inhibition of antigen-antibody reaction: application for measuring {alpha}2,6-sialylated glycoforms of transferrin

01-09-2013 | Kyoka Hoshi; Yoshinobu Kariya; Kiyomitsu Nara; Hiromi Ito; Kana Matsumoto; Masamichi Nagae; Yoshiki Yamaguchi; Madok ..., Journal of Biochemistry, 2013

We developed a high-throughput Enzyme-linked immunosorbent assay (ELISA) for measuring α2,6-sialylated transferrin (Tf), based on inhibition of anti-Tf antibody binding to α2,6-sialylated Tf by a lectin, Sambucus sieboldiana Agglutinin (SSA). The inhibition was not observed with other glycoforms, ...


Correlation between Particle Deformation Kinetics and Polymer Interdiffusion Kinetics in Drying Latex Films

29-08-2013 | Katja Pohl; Jörg Adams; Diethelm Johannsmann, Langmuir, 2013

Using an experimental setup which determines the turbidity of the sample and the efficiency of Förster resonance energy transfer (FRET) at the same time, we have correlated the particle deformation kinetics in a drying latex film, quantified by light scattering with the kinetics of polymer ...


Facile Preparation of Raspberry-Like Superhydrophobic Polystyrene Particles via Seeded Dispersion Polymerization

26-08-2013 | Rui-kun Wang; Hua-rong Liu; Feng-wei Wang, Langmuir, 2013

A simple and facile approach was developed to fabricate raspberry-like or snowman-like particles via seeded dispersion polymerization by just changing the ratio of second monomer styrene (St) to seeds in which poly(styrene-co-hydrolyzed-methacryloxypropyltrimethoxysilane) [P(St-co-MPS)] latex was ...


Effect of the Incorporation of Modified Silicas on the Final Properties of Wood Adhesives

23-08-2013 | Audrey Bonnefond, Yury Reyes, Pablo Peruzzo, Erik Ronne, Joanna Fare, Maria Paulis, Jose Ramon Leiza, Macromolecular Reaction Engineering, 2013

The effect of the incorporation of three different surface modified silicas on the final properties of poly(vinyl acetate) (PVAc) latex based wood adhesives is assessed. It is shown that the compatibility and reactivity of the silica with the polymer determines its state of dispersion ...


Structure of the processive rubber oxygenase RoxA from Xanthomonas sp [Biochemistry]

20-08-2013 | Julian Seidel; Georg Schmitt; Maren Hoffmann; Dieter Jendrossek; Oliver Einsle, Proceedings of the National Academy of Sciences current issue, 2013

Rubber oxygenase A (RoxA) is one of only two known enzymes able to catalyze the oxidative cleavage of latex for biodegradation. RoxA acts as a processive dioxygenase to yield the predominant product 12-oxo-4,8-dimethyl-trideca-4,8-diene-1-al (ODTD), a tri-isoprene unit. Here we present a ...


Structure and Dynamics of Soft Repulsive Colloidal Suspensions in the Vicinity of the Glass Transition

08-08-2013 | Jérôme J. Crassous; Lucia Casal-Dujat; Martin Medebach; Marc Obiols-Rabasa; Romaric Vincent; Frank Reinhold; Volodym ..., Langmuir, 2013

We use a combination of different scattering techniques and rheology to highlight the link between structure and dynamics of dense aqueous suspensions of soft repulsive colloids in the vicinity of a glass transition. Three different latex formulations with an increasing amount of the hydrophilic ...


Online conductivity and stability in the emulsion polymerization of n‐butyl methacrylate: Batch versus semibatch systems

07-08-2013 | Funian Zhao, E. David Sudol, Eric S. Daniels, Andrew Klein, Mohamed S. El‐Aasser, Journal of Applied Polymer Science, 2013

ABSTRACT A homemade resistance probe (R) and a torroidal probe (T), which work on different principles to measure conductivity, were used as online sensors to monitor conductivity during the course of emulsion polymerizations of n‐butyl methacrylate (BMA). Six batch emulsion polymerizations of ...


Reinforcing potential of nanofibrillated cellulose from nonwoody plants

07-08-2013 | Ashraf Chaker, Pere Mutje, Fabiola Vilaseca, Sami Boufi, Polymer Composites, 2013

In the present work the reinforcing potential of nanofibrillated cellulose (NFC) from five different non‐woody plants, namely; abaca, sisal, hemp, jute and flax was investigated. Nanocomposite materials were prepared by casting a mixture of NFC suspension and a polymer waterborne latex ...
